Abstract
The research on \(K^{\ast}(892)\) meson production can lead to new discoveries in properties of exotic state of matter called quark–gluon plasma (QGP) in which quarks and gluons are deconfined. Strangeness enhancement is one of the main observables of QGP which can be measured by studying the production of particles containing strange quark(s). \(K^{\ast}(892)\) meson is one of such particles. Production of \(K^{\ast}(892)\) can be described by its invariant \(p_{T}\) spectra. Comparison of production of \(K^{\ast}(892)\) in heavy and in \(p+p\) collision systems can be shown by nuclear modification factors. Since QGP isn’t formed in \(p+p\) collisions at \(\sqrt{{}^{S}NN}\) GeV strangeness enhancement can be observed through the nuclear modification factors. Current report is dedicated to measurements of \(K^{\ast}(892)\) meson’ invariant \(p_{T}\) spectra and nuclear modification factors as functions of transverse momentum and centrality in Au \(+\) Au collision system at \(\sqrt{{}^{S}NN}\) GeV.
